"We should also be comforted by the time of the year. This is the end of the flu season, not the beginning. Flu viruses thrive in the low humidity of winter, not summer. It is very likely that this outbreak will die out automatically as the summer comes. It will remain necessary to track it because it could reappear in the fall, but it is very unlikely that it will erupt into a pandemic this summer.
I am glad that this outbreak is a swine rather than a bird flu, not because pig viruses are intrinsically safer than bird viruses, but because the greater lesson to guide us here comes from the 1976 pig hysteria, rather than from the 1918 bird flu plague."
